Now that devfs is removed, there's no longer any need to document how to do this or that with devfs. This patch includes some improvements by Joe Perches. Signed-off-by: Adrian Bunk <bunk@stusta.de>

Module options
|
|
--------------
|
|
|
|
The mwave module takes the following options. Note that these options
|
|
are not saved by the BIOS and so do not persist after unload and reload.
|
|
|
|
mwave_debug=value, where value is bitwise OR of trace flags:
|
|
0x0001 mwavedd api tracing
|
|
0x0002 smapi api tracing
|
|
0x0004 3780i tracing
|
|
0x0008 tp3780i tracing
|
|
|
|
Tracing only occurs if the driver has been compiled with the
|
|
MW_TRACE macro #defined (i.e. let EXTRA_CFLAGS += -DMW_TRACE
|
|
in the Makefile).
|
|
|
|
mwave_3780i_irq=5/7/10/11/15
|
|
If the dsp irq has not been setup and stored in bios by the
|
|
thinkpad configuration utility then this parameter allows the
|
|
irq used by the dsp to be configured.
|
|
|
|
mwave_3780i_io=0x130/0x350/0x0070/0xDB0
|
|
If the dsp io range has not been setup and stored in bios by the
|
|
thinkpad configuration utility then this parameter allows the
|
|
io range used by the dsp to be configured.
|
|
|
|
mwave_uart_irq=3/4
|
|
If the mwave's uart irq has not been setup and stored in bios by the
|
|
thinkpad configuration utility then this parameter allows the
|
|
irq used by the mwave uart to be configured.
|
|
|
|
mwave_uart_io=0x3f8/0x2f8/0x3E8/0x2E8
|
|
If the uart io range has not been setup and stored in bios by the
|
|
thinkpad configuration utility then this parameter allows the
|
|
io range used by the mwave uart to be configured.
|
|
|
|
Example to enable the 3780i DSP using ttyS1 resources:
|
|
|
|
insmod mwave mwave_3780i_irq=10 mwave_3780i_io=0x0130 mwave_uart_irq=3 mwave_uart_io=0x2f8
|
|
|
|
Accessing the driver
|
|
--------------------
|
|
|
|
You must also create a node for the driver:
|
|
mkdir -p /dev/modems
|
|
mknod --mode=660 /dev/modems/mwave c 10 219
|
|
|
